A portable battery charger including power banks (with built-in lithium batteries) used to recharge the lithium-ion batteries contained in equipment, such as mobile phone, is considered a spare lithium battery and must not be placed in your check-in baggage.
Do airlines check powerbanks?
Most airlines allow passengers to bring power banks in their carry-on luggage, but not in checked baggage, due to the risk of fire caused by lithium-ion batteries. The capacity of the power bank is also typically limited to 100 watt-hours or 20,000mAh.
Does TSA check portable chargers?
What needs to be removed from carry-on for TSA?
Remove your shoes and place them directly on the X-ray belt. Remove personal electronic devices larger than a cell phone from your carry-on bag and place them into a bin with nothing placed on or under them for X-ray screening. (E.g. laptops, tablets, e-readers and handheld game consoles.)
What TSA items are confiscated?
When you leave a confiscated item behind with the TSA, it automatically becomes government property. The guidelines airports follow for either disposing of, holding, or moving the item along to another service area are determined by the U.S. General Services Administration.
